Sex and age-related differences in chronic rhinosinusitis with nasal polyps electing ESS.

ABSTRACT

PURPOSE: Sex and age of patients are variables affecting across the board all chronic rhinosinusitis with nasal polyps (CRSwNP) endotypes. The main aim of this investigation was to compare the clinical, laboratory, pathological and prognostic characteristics of CRSwNP in male vs female patients stratified according to age (young-adult [20 years ≤ age ≤ 40 years], and elderly [age ≥ 65 years]). This is the first study that analyzed the association of the above-mentioned features with age and sex combination in CRSwNP electing endoscopic sinus surgery (ESS). MATERIALS AND METHODS: One hundred and five consecutive young-adult patients (62 males and 43 females) and 67 elderly patients (44 males and 23 females) with CRSwNP who had undergone ESS were enrolled. RESULTS: The recurrence rate resulted associated with the age and sex combination (p = 0.0165). Young-adult males' recurrence rate (29.0%) was higher than young-adult females (11.6%) and elderly males (4.5%). Allergy resulted associated with age and sex combination (p = 0.0158). Young-adult males' allergy rate (50.0%) was higher than elderly males' (29.5%) and elderly females' (13%). Moreover, allergy rate was higher in young-adult females (41.9%) than in elderly females. CONCLUSION: Our data suggest the possibility of an interaction between sex and age in the recurrence of nasal polyposis after ESS. More studies are needed to understand the role of sex hormones in pathogenesis and prognosis of CRSwNP.
